I upgraded plex using the plugin.
The service didn’t start on its own so I started it manually. Then I was able to access the IP address and it asked for a new name. I gave it the same name that it should’ve had, but then I closed the tab in fear I was overwriting something.
The previous data all seems to be available in Plex Media Server, but now in the web interface it shows my old server as inaccessible, but a new server with the same name is accessible but has 0 libraries.
Does anyone know how to re-link this “new” server to the data that appears to be in Plex Media Server? It would be a really big pain to rebuild this server. Thank you.
I believe the data is still actually there based on snooping the Plex Media Server directory and finding a few things that are from earlier in June, such as the files in the plug-in support/databases directory.
Thank you for any assistance in this.

Edit 1: adding more information as I learn more. Looking in my Preferences.xml file, I see the “processedmachineidentifier” as 00a3…
When I’m looking at the Plex settings window of my list of servers, there are 2 now with the same name. One is available and has 0 libraries, and the old one which is unavailable. When I hover over the link to the old server, I can see the URL is the matching identifier as to what is in my preferences.xml file above (00a3…), while the new, available server, is some other ID (ff2d…) that I have no idea where it is pulling from. So that is what I’m trying to figure out. It appears all my data is still there but I don’t know where this plexmediaserver service instance is pulling from.
Edit 2: Just keeping this updated. Used the restoration process on the database backups I had but do not think it changed anything. I did read that the information in those files was progress/watched status, more organizational information rather than any metadata like detailed information about what libraries the server should have. Seems I don’t understand too much here unfortunately. I am likely going to end up remaking the libraries. I double checked that the jail has the proper mount. Did remake one library on it so far but didn’t see any previous database information being applied to it, so probably will just be remaking it all from scratch. On the bright side I noticed that the scanning/matching/analyzing is about 500% faster than the last time I did this, so I’m glad to see that. Maybe this won’t actually be very difficult after all. Sorry I didn’t find a solution.
